On a piece of rectangular paper 20 cm long and 12 cm wide, cut out the largest triangle. The bottom of the triangle is () cm, the height is () cm, and the area is () cm

The largest triangle can be obtained by connecting the diagonals of the rectangle, with the bottom or height of 20cm or 12cm respectively. According to the triangle area formula, the area is 120cm2 when the bottom multiplied by the height divided by two

Cut out the largest triangle on a 20 cm long and 16 cm wide rectangular paper. What's the area of the triangle?

First, calculate the area of the rectangle, 20 * 16 = 320 (cm2). The largest triangle bottom should be the length of the rectangle 20cm, the height is its width 16cm, and the area is 20 * 16 △ 2 = 160 (cm2)
